Abundances of Na, Al, and α elements as a function of RG. Our results (filled blue circles) are compared with those of Yong et al. (2006, YON, cyan asterisks), Luck et al. (2011, LII, magenta crosses), Luck & Lambert (2011, LIII, open green circles), and Lemasle et al. (2013, LEM, red triangles). The blue solid line shows the linear regression of our Cepheid sample, and the black dashed line the linear regression of the entire Cepheid sample. The blue error bars display the mean spectroscopic error of the current sample. The abundances available in the literature have similar errors.
